Abstract

A utility knife includes a slidably retractable knife blade, which is moving into and out of the knife body by a sliding mechanism on the side of the body. The knife blade is held by a carrier and secured to the carrier by a two-pronged lever, where a shorter one of the prongs is moved within a slot in the knife blade to secure the blade. The blade is released by pressing the longer one of the prongs to move the shorter prong out of the slot. A light in the body is located below the knife blade to enable the user to illuminate a work area while using the knife.

Another disadvantage is that a top sliding mechanism may not be convenient for some users due to placement.

[0005] Another feature of utility knives is the release mechanism for the blade to allow...
